Inside of the cathedral in Saintsbridge, you will find a cleric who needs some help. It seems some ruffian has been extorting coin from travelers on their way to Saintsbridge. Said ruffian can be found right outside of the city, in East Saintsbridge Traverse. Using Olberic or H’aanit, defeat the ruffian in a duel, who has a strength of four (so shouldn’t be too difficult) and you will complete the quest.
